JOINTED POLE.

SPECIFICATION forming part of Letters Patent No. 709,924, datedSeptember 30, 1902.

Application filed July 16, 1902. Serial No. 115,807. (No model.)

To all whom it'm/ay concern:

Be it known that I, MARTIN NELSON, residing at Emerson, in the county ofMills and State of Iowa, have invented certain useful Improvements inJointed Poles; and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame,

reference being had to the accompanying drawings, which form a part ofthis specification. V

This invention relates to a new and novel improvement in jointed poles.

The object of my invention is to provide a jointed pole adapted to beused in connection joint members.

- stance.

My invention embodies, essentially, a male socket member comprising thehollow housing B, adapted to receive the end of one portion of the poleused in this device. This male member is provided with the projectingsocket portion 1), perforated so that a bolt or pin 4 will pass throughthe same, While the projecting plates 0 c are provided, by means ofwhich this member B is secured to the pole-section D, as disclosed inFig. 2, for in- These extending portions 0 c are also perforated, sothat thebolt 15 willreadily pass through the same in order that thepole-section D may be secured. Secured to this male member B is aslotted or notched annulus or ring 5, whichis reinforced by a transversebar f, (shown in Fig. 3,) and in order to secure the extending portions0' to the ring 5v I provide the ears or lugs 12. (Shown in Fig. 2.)Working in conjunction with this male member is a female joint portionof the member A, provided with aperforated socket adapted to receive thetongue b, this major portion A of this joint member being perforated, sothat the bolt 4 will readily pass through the two united members A andB. This member A is also hollow, so as to provide a housing into whichthe end of the pole D fits. Extending from this housing A are the platesa, which are perforated, so that the bolt 13 maybe inserted to securethe same to the pole D. Below I provide the ear 6, within which is heldthe end of the bar 7, guided at the other end within the ear 10, aspring 9 normally forcing this bar 7 inward into'engagement with thenotched annulus 5. Extending from this housing A is an annulus 5,provided with a central strengthening-bar g, as shownin Fig. 4, while atopposite points are provided the stops 12, adapted to come in engagementwith the plates 0 should the joint be turned too far to the right orleft. In order to secure the ring 5 to the platesa, I provide thestrengthening-ears 3, as shown in.

Fig. 5. A suitable chain to extends from this locking-pin 7 and is ledto any suitable point, so that the operator may readily throw out ofengagement this locking-pin 7 to release the same. From this it will benoticed that each joint member is provided with an aunulus, held bymeans of the pin 4:,which passes through the transverse bars f and g,secured to these rings 5 and 5, so that the pole may be broken at asuitable point, permitting the draft-animals to be turned to the rightor left Without moving the implement to which the jointed pole issecured.

In Fig. 5 the seating a: is shown, into which the end of the pole -tip Dfits. The joint member is provided with a similar opening, so that thesemembers A and B form, in efiect, housings, into which the ends of thepole members D and D work. The male joint member B is provided with theprojecting lip 1, adapted to ride over the annulus 5 to prevent the samefrom springing up'at the point of contact with this member B, While theholder 6 is projected upon the oppositeside to lap over the annulus 5.

The bolt 4 is slotted at. the end below and provided with a cotter-pin eto removably hold the same, and,

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is

In a joint for poles, the combination with said male member beingnotched, and a latch secured to said female member adapted to engageWithin the notches of the annulus secured to said male member, as andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

MARTIN NELSON.
